Abstract
It is at least one carrier layer and the flexible sheet Nian Jie with carrier layer and elastically extensible along lead at least in the region of flexible sheet including laminate the present invention relates to a kind of elastic diaper component;Laminate has the first connecting pin and second connection end;Second connection end has the width smaller than the first connecting pin transverse to lead;It is connected in Hookean region of the carrier layer between two connecting pins with flexible sheet by the multiple parallel strip of glue extended transverse to lead;Strip of glue forms pattern of adhesive, described adhesive pattern is in the region of adjacent second connection end than having wider strip of glue and/or the smaller spacing between adjacent strip of glue in the region of adjacent first connecting pin, it is characterized in that, the width of strip of glue and/or the spacing between adjacent strip of glue are so determined according to laminate width so that the extension of Hookean region is substantially consistent when laminate is stretched along lead.
Description
Technical field
The present invention relates to a kind of elastic diaper components, and including laminate, the laminate has at least one carrier layer
The flexible sheet be bonded with carrier layer and elastically extensible along lead at least in the region of flexible sheet.Laminate
With the first connecting pin for being fixed on diaper and the second connection end for blocking element, wherein, the second connecting element
It is less than width of first connecting pin transverse to lead transverse to the width of lead.Elasticity between two connecting pins
In region, carrier layer is connected with flexible sheet by the multiple parallel strip of glue extended transverse to lead.It is such
Diaper component is often also referred to as diaper hanging ring (back ear laminat) in practice.
Background technology
Elastic diaper component with characteristics mentioned above is for example as known to 2006/124337 A1 of WO.For connecting
The adhesive of flexible sheet with for example made of adhesive-bonded fabric carrier layer formed be made of many parallel strip of glue it is viscous
Mixture pattern, described adhesive item extend transverse to lead.It is bonded compared to planar, described adhesive pattern improves lamination
The elastic extensibility of piece.In general, the Hookean region of diaper component is mechanically activated by stretching.Strip applies adhesive and improves
It can activity and the validity of activation.In the scope of known means, the strip of glue of pattern of adhesive has identical width
And it is set with predetermined constant spacing.According to 2006/124337 A1 of WO, between the width of strip of glue and each item between
Away from being determined with the fixed proportion in the scope between 0.33 and 1.0.
2 158 888 A1 of EP are related to a kind of laminated width material, can be from the laminated width according to multiduty process for stamping
Diaper component is gone out in material.Laminated width material has elastic carrier foils and adhesive-bonded fabric coating, wherein, each layer is mutually bonded.
Laminated width material has the region that is mutually bonded of planar and the region of strip bonding.Strip of glue forms a kind of pattern, the pattern
Strip of glue that is with different in width and/or being set with different spacing.Pattern of adhesive is not accounted for herein by laminated width material
The shape for the diaper component gone out.
Formerly it is to make one satisfied ductility the advantages of known laminate, if real on the lamination item of constant width
If applying strain measurement.In tension test is carried out to testpieces (being usually standardized in terms of in its size), one can be measured
The ductility of cause.
It is being produced in batches as so-called diaper hanging ring and is having to be fixed on the first loose connecting pin on diaper
It is observed in the diaper component of the narrow second connection end for blocking element, prolonging when laminate is stretched along lead
It opens up uneven.On narrow connecting pin, the Hookean region of diaper component is subjected to larger tensile load and than the neighbour of laminate
The Hookean region for connecing wide connecting pin extends stronger.It needs preferably to extend near wide connecting pin, and in the second connection
Higher intensity is made every effort on end.
The content of the invention
